Readable

What is Readable?
Readable translates PDF files into Japanese while keeping the original layout intact, including tables, figures, and images. Built by NextLab Inc., it targets researchers reading academic papers and business teams working through manuals, reports, and contracts without rebuilding documents by hand.
The reader shows original and translated text side by side so you can scan a translation and jump back to the source line when something needs a closer look. Premium users can register custom dictionaries so product names, abbreviations, and field-specific terms translate the same way every time.
Readable runs in the browser and through a Chrome extension for quick file translation. Pro Standard focuses on English-to-Japanese PDFs, while Pro Premium adds 200+ source languages, larger file limits, and optional ChatGPT-based translation engines.
